S.A.D – Heat sensitive T-shirt

heat_sensitive_T_Shirt.jpgS.A.D stands for ‘Seasonal Affective Disorder’ or also known as winter depression, is a mood disorder whose sufferers experience normal mental health throughout most of the year, but experience depressive symptoms in the winter when it is darker and less sunshine.

I think I am not suffering from SAD but I do like to be as much and long as possible in summer like conditions.

To help a friend who does suffer under SAD, graphic designer Keith Hancox designed the S.A.D T-shirt 01 for him, where the sun image is over printed with black heat sensitive ink which turns transparent at 32Âșc. So as soon as the temperature raises to this level the sun will shine for his friend, cheering up his mood and hopefully minimize the SAD symptoms.

The S.A.D T-shirt is not exactly related to wearable electronic but I like the idea heat sensitive ink is used and imagine what cool effects could be made using conductive textiles underneath that warm up when supplied with electrical power. The heating up could be controlled via sensor input for example of heart rate to show ‘sensible’ design effects. Got it?
